A tragic accident leaves a teenager in a coma. But a Louisville mother says a Jefferson County high school is responsible. The woman believes school officials didn't do enough to protect her daughter.

The mother in this case is filing a lawsuit claiming her 14-year-old daughter was allowed to cross a busy road and get hit by a car. Tina Hilbert says her daughter Sara was on the academic team at school and wanted to be a marine biologist.

In December, Hilbert's daughter Sara was a freshman and in the orchestra at Moore High School, playing the violin.

While attending an evening concert, Sara and a friend asked their teacher for permission to walk across the street to Burger King. Tina Hilbert says, "I lost my life in one second over a hamburger."

The two never made it. Hilbert explains, "Sara is in a persistent vegetative state."

According to a Metro Police report, Sara and her friend made it to the center lane of the Outer Loop when they were "motioned by the bus driver to cross." But when she stepped past the bus, another vehicle struck her.

But should officials with the school be responsible for what ended up being a tragic decision made by a 14-year-old girl? The family's attorney Brett Oppenheimer says, "When this child approached this teacher and said can we run across the street and grab something to eat, the answer should have been no."

No charges were ever filed in the case. But Hilbert is suing Moore High school's Site-Based Decision Making council, a former principal, the orchestra teacher, and bus driver.

Oppenheimer asks, "Was the bus driver responsible for waving them across, and if so to what extent? Was the teacher responsible for saying yeah, run across the Outer Loop, just make sure you get back in time?"

Meanwhile, Tina Hilbert says the problem is the crosswalk doesn't have lights. But she hopes her lawsuit will change that: "I don't want another family to ever go through what we've had to go through."

Fox 41's Stephan Johnson spoke with a representative from Jefferson County Public Schools, and it is their policy not to comment on pending litigation.
